ことによって、面倒な液泡作業を省略し、シートの製造
上の合理化を図るものである。(Prior art) Seats with integrally molded skins eliminate the troublesome foaming process and streamline the production of seats by attaching the skin material to the pads that make up the seat cushion and seat back. It is.
ところで、シートの表面に部分的に凹凸模様を何形する
場合は、一般には加熱プレス方法か、高周波ウエルダ方
法が採用されているが、これは一般に表皮材とパッドが
別体のタイプのものであり、例えば、特開昭６０−１６
０９９０号公報に示す技術がある。By the way, in order to partially create uneven patterns on the surface of a sheet, a heat press method or a high frequency welding method is generally used, but this method generally involves a type in which the skin material and pad are separate parts. Yes, for example, JP-A-60-16
There is a technique disclosed in Japanese Patent No. 0990.
この種の模様を形成した表皮材を用いて表皮一体成形す

の模様に対応する凹凸を刻設し、表皮材を該凹凸に位置
決めする方法であり、これによって、別体タイプと同様
な外観のシートを得られる。When integrally molding the skin using a skin material with this type of pattern, what is usually considered is to carve unevenness corresponding to the pattern of the skin material on the mold surface of the lower mold, and position the skin material on the unevenness. By this method, a sheet with an appearance similar to that of a separate type can be obtained.

形成されるようにした点を要旨とづる。(Means for Solving the Problems) In order to achieve the above object, the present invention lays a skin material on the mold surface of a lower mold, then engages an upper mold with the lower mold, and forms a material between the two. In a method of injecting a foamable resin liquid constituting a pad into a molded cavity, filling the cavity without foaming, and molding a sheet with an integrated skin material on the surface: In addition to carving the unevenness constituting the pattern, a boss portion for hot press provided with unevenness that engages with the unevenness is provided protrudingly at a position facing the unevenness of the upper mold, and the above skin material is sandwiched in the mold clamping state. The gist of the present invention is that a surface pattern corresponding to the irregularities is formed on the surface of the skin material by the engagement of the irregularities.
（作用）
型締した状態で自動的に表皮材の所定の位置に凹凸模様

様がずれることがない。(Function) When the mold is clamped, an uneven pattern is automatically formed at a predetermined position on the skin material, and since foam molding is performed in this state, the uneven pattern does not shift.
（実施例）
以下、この発明の一実施例を図面を用いて詳細に説明す
る。(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.
第１図はこの発明方法を適用した発泡成形型を示してい
る。FIG. 1 shows a foam mold to which the method of this invention is applied.
図において、１はシートクッションの表面形状に応じて
概略船底形をした下型、２は該下型１の上面開口部に係
合する上型である。In the figure, numeral 1 denotes a lower mold approximately shaped like a ship's bottom according to the surface shape of the seat cushion, and numeral 2 denotes an upper mold that engages with the upper opening of the lower mold 1.
下型１の型面の中央位置には表面模様形成用の凹凸３が
刻設されている。In the center of the mold surface of the lower mold 1, an unevenness 3 for forming a surface pattern is carved.
これに対応して上型２の下型には加熱プレス用のボス部
４が出没可能に突設され、その下面には前記凹凸３に係
合する凹凸５が刻設されている。Correspondingly, a boss portion 4 for hot pressing is provided on the lower mold of the upper mold 2 so as to be retractable and protrusive, and an unevenness 5 that engages with the unevenness 3 is carved on the lower surface of the boss portion 4 .
前記ボス部４は図示しない油圧シリンダ等によってキャ
ビティｄ内に胃降可能に保持されるものであって、その
内部には加熱用のヒータ６が内蔵され、下型１の型面に
敷設される表皮材７を加熱するようにしている。The boss portion 4 is held removably within the cavity d by a hydraulic cylinder or the like (not shown), and a heater 6 for heating is built inside the boss portion 4, and is placed on the mold surface of the lower mold 1. The skin material 7 is heated.
表皮材７は例えば塩ビレザーの如き熱可塑性のシートの
裏面にワディングを衷打ちした、この優の成形に通常用
いられる人口皮革であって、加熱。The skin material 7 is an artificial leather that is usually used for molding this product, and is made by sewing wadding on the back side of a thermoplastic sheet such as PVC leather, and is heated.
加圧によって、前記凹凸３．５の形状に応じた形状に付
形される。By applying pressure, it is shaped into a shape corresponding to the shape of the unevenness 3.5.
次に、以上の構成の発泡成形型を用いた成形手順を説明
する。Next, a molding procedure using the foam mold having the above configuration will be explained.
まず、上下型１．２が型開している状態で、表皮材７を
下型１の型面にセットし、次いで上型２を係合する。こ
れによって、前記表皮材７の端末は上下型１，２の周縁
にピンチされ、固定状態となる。First, with the upper and lower molds 1.2 opened, the skin material 7 is set on the mold surface of the lower mold 1, and then the upper mold 2 is engaged. As a result, the ends of the skin material 7 are pinched to the peripheries of the upper and lower molds 1 and 2, and are in a fixed state.
次いで、ボス部４を突設させ、両凹凸３，５間に表皮材
７を挟んだ状態でヒータ６を加熱すると、表皮材７には
凹凸３，５の形状に沿った模様が形成される。Next, when the boss portion 4 is protruded and the heater 6 is heated with the skin material 7 sandwiched between both the unevenness 3 and 5, a pattern that follows the shape of the unevenness 3 and 5 is formed on the skin material 7. .
次にヒータ６を切り、上下型１，２間に形成されたキャ
ピテイｄ内でウレタン原液などの発泡性樹脂液を発泡さ
せつつボス部４を上背させれば、発泡樹脂は形成された
凹凸模様の裏面に旧り込み、模様を定着させる。Next, the heater 6 is turned off, and the foamed resin liquid such as urethane stock solution is foamed in the cavity d formed between the upper and lower molds 1 and 2 while the boss portion 4 is turned upward. Folds into the back side of the pattern and fixes the pattern.
その後上型２を取り外し、製品を脱型すれば、第２図に
示すごとく表皮材７の表面の所定位置に凹凸模様１２を
形成し、かつ裏面にバッド１４を一体化したシートクッ
ション１０を得られるのである。After that, the upper mold 2 is removed and the product is demolded to obtain a seat cushion 10 with an uneven pattern 12 formed at a predetermined position on the surface of the skin material 7 and a pad 14 integrated on the back surface as shown in FIG. It will be done.
なお、前記実施例ではボス部４をＲ降可能としているが
、小面積の場合には凹凸模様の裏面にパッドを一体化す
る必要らないので、この場合には、ボス部４を上型２の
下面に一体化し、発泡と同時に凹凸模様のみを形成して
し良い。In the above embodiment, the boss part 4 can be lowered in the R direction, but in the case of a small area, it is not necessary to integrate the pad on the back surface of the uneven pattern. It may be integrated with the lower surface of the foam to form only the uneven pattern at the same time as foaming.

以上実施例によって訂細に説明したように、この発明の
方法によれば、表皮一体成形シートの成形と同時に表皮
材の表面に凹凸状の模様を何形できるので、従来の別工
程で凹凸を形成する方法に比べて工程が一工程でよく、
大幅４【省略ができる。(Effects of the Invention) As explained in detail through the examples above, according to the method of the present invention, any number of uneven patterns can be formed on the surface of the skin material at the same time as forming the skin integrally molded sheet. Compared to the method of forming unevenness in separate steps, only one step is required.
Significantly 4 [Can be omitted.
